The Sun Hydraulics DMDAMNN614 (DMDAMNN614) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a rapid response time of approximately 50 ms, ensuring swift and efficient operation. The DMDAMNN614 valve incorporates a closed transition between spool positions B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, enhancing its versatility in various hydraulic systems. Equipped with EPDM seals, this model is specifically suited for systems using phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design of the solenoid tube allows the working fluid to cool the armature, although prolonged energization can lead to fluid breakdown in certain conditions. This model also features interchangeable coils compatible with other Sun Series 1 solenoid products and includes manual override capabilities with a detent mechanism designed for temporary actuation. The manual controls on models equipped with D or L control are rated for approximately 7,000 cycles, indicating robustness for repeated use. Sun Hydraulics' floating style construction minimizes internal part binding due to installation torque or machining variations, further enhancing this valve's reliability and performance in demanding applications. This makes the DMDAMNN614 an excellent choice for advanced hydraulic systems requiring high precision and durability.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
